TALKING-MACHINE ATTACHMENT.

Application filed August 28 1912. Serial No. 717,608.

To all whom it may concern:

Be it known that I, l/VILLIAM O. HOLLAND, a citizen of the United States, residing at Niagara Falls, in the county of Niagara and State of New York, have invented new and.

useful Improvements in Talking-Machine Attachments, of which the following is a specification.

y This invention relates'to talking machine attachments and the principal object of the invention is to provide a simple and eflicient device for automatically stopping the rotation of the record and for lifting the needle therefrom.

A further object of the invention is to provide a device of this character which-may be adjusted for use on different sized records and for use on diflerent types of machines so that the attachment may be sold for'universal use.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which Figure 1 is a top plan view showing the attachment applied to an ordinary disk talking machine. Fig. 2 is a side elevation thereof. Fig. 3 is a bottom plan view of the attachment removed. Fig. 4 is a horizontal sectional view through the attachment.v Fig. 5 is a perspective view of the tripping dog su ortin head removed from the attachmeut. Fig. 6 is a perspective view of'the reproducer lifting arm removed. Fig 7 is a detailed edge elevation of said arm showing its association with the reproducer or sound box. Fig. Sis a side elevation showing the position of the parts when operated.

Referring more particularly to the drawing, l represents the ordinary table of a disk talking machine which is mounted upon the driving shaft 2 thereof, said driving shaft projecting above the table, as is usual to center the record 3 thereon, as is'customary. The attachment comprises a circular weighted base 4 having a central socket 5 in its under side to receive the projecting end The bottom of the base 4 has suitable fliction pads 6 arranged thereon so as to engage the face of the record and to cause the base-torotate with the record and to prevent scratching of the same. The base is provided with a vertical head 7 by which the same can be manipulated and is provided with a notch 9 in its side, as shown.

Specification of Letters Patent.

Patented Feb. 17,1914.

Extending inwardly from the inner wall'of the notch are separated apertures 10 in.

which are slidable the supportingpins 11 carrying upon their outer ends the adjusting head 1 This adjusting head has a set screw passing into the same from the under side-which holds the gage plate 13 in adusted position. This gage plate is used-to.

determine the distance between the needle of the sound box and the tripping arm, as will be hereinafter described.

The head 12 is provided with a horizontal shelf 14 and pivoted to the. head above the shelf is a tripping dog 15 having a diago-v nally projecting finger 16 formed on one end and the opposite pnd provided with ya notch 17. v

The tripping arm comprises av circular centrally apertured head 18 having diaa metrically opposite arcuate slots 19 formed therein and a tangentially extending arm 20 having a laterally projecting pin 21 on its outer end. This arm is adjustably secured to the reproducer 22 by means of a plate 23 which has screws 24 passing therethrough and through the arcuate slots 19 and being threaded into the reproducer, By loosening the screws, it will be seen that the plate 18 may be turned on the reproducer and-the vertical adjustment of the pin 21 readily obtained.

In the operation of the device, the gage plate 13 is properly adjusted laterally on the head 12 so as to determine the distance between the needle and the end of the pin 21 and held in'such position by the set'screw 13 which is threaded into the head 12. The base is then placed upon a record andthe head 12 adjusted so as to bring the point of the gage plate 12 inalinement with the last inner groove on the record. The machine is then started in operation, as is usual, with the. dog in the position shown in full lines in Fig. 2. When the needle is traveling in the last inward groove of the record, the pin will be brought into engagement with the finger 16 and the dog will be tilted to'the position shown in dotted lines in Fig.2.v The disk and base will then make one'more complete revolution when the pin will be in position to engage the notch 17 formed in the forward end of the dog. The dog in turning on its pivotal point will raise the pin 21 and thereby the tripping arm 20 and; the

sound box thus lifting the needle fromthe record and preventing the same from scratching. The friction of the rubber pads 6 upon the record and the friction of the record upon the table will be sufficient to stop the rotation of the machine until the operator can apply the brake.

What is claimed is I. An attachment for disk talking machines provided with a rotating disk, sound box and needle comprising a Weighted mounting member removably carried upon the disk of the machine, a radially adjustable head carried by the mounting member, an adjustable gage plate carried by the head, a tripping dog pivotally mounted upon the headfor vertical movement, and an arm adjustably secured to the sound box of the machine and adapted to engage the tripping dog, said dog and arm coacting to raise the sound box when the needle thereof reaches a predetermined point in its travel over the disk.

2. An attachment for disk talking machines provided with a rotating disk and 1 sound box comprising a Weighted mounting member adapted to be removably carried upon the disk of the talking machine, a laterally adjustable head carried by the mounting member, an adjustable gage plate carried by the head, a tripping dog pivotally mounted upon the head for vertical movement and having a diagonally offset end and a notch in the opposite end, an arm adjustably secured to the sound box of the machine and a laterally extending pin on said arm adapted to engage the offset end on the dog to immediately operate the same, said pin adapted to engage in the notch and further operate the dog to the limit of its movement whereby the sound box Will be raised and the rotation of the disk stopped.

In testimony whereof I afiix my signature in presence of two Witnesses.
